熊猫行汇总

I am trying to parse and organize a trading history file.
I am trying to aggregate every 3 or 4 rows that has the same Type: BUY or SELL together if they come after each other only. and if they don't then I want to take only one row.
as you can see the example below those multi-buy trades I want them to be aggregated within one row which after it will come another one row of sell trade.
in a new df with aggregated trades prices, and amounts. link for csv: https://drive.google.com/file/d/1GoDRdI7G8uJzuLoFrm5InbDg23mAwW6o/view?usp=sharing
